The purpose of the report is to share our experience with the technique of Leung et al. (2001), who used trephines for the treatment of scaphoid nonunion.
We suggest that 4 mm be used as a reference value for the evaluation screw length at the safe zone. If the vertical distance between a distal screw tip and the peak of the Lister tubercle is lesser than 4 mm on a fluoroscopic or plain X-ray true lateral image, dorsal cortical penetration should be suspected. When dorsal cortical penetration at the hazard zone is suspected, both oblique or pro-supination views should be checked.

Pyogenic arthritis is difficult to treat and can make severe sequelae in the joints. We report a case of pyogenic arthritis of the hand that occurred after human bite injury in adolescent treated with wide debridement and external fixator. Our literature searches revealed that the use of external fixator is good treatment option for the treatment of pyogenic arthritis of the hand.
Purpose: A rupture of extensor pollicis longus tendon is a common complication that may occur after distal radius fracture but risk factors are still elusive. Systemic risk factors of extensor pollicis longus tendon rupture in distal radius fracture were investigated. Methods: We retrospectively reviewed 30 patients of extensor pollicis longus tendon rupture after distal radius fracture from February 2010 to March 2016. Three times more patients for the control group with matched sex, age and type of fracture without extensor pollicis longus tendon rupture were chosen during the same period. We statistically analyzed systemic risk factors of spontaneous tendon rupture, such as low bodyweight, diabetes mellitus, rheumatoid arthritis, thyroid disease, systemic steroid use, local steroid injection around wrist, quinolone, and statins. Results: The incidence of extensor pollicis longus tendon rupture was significantly higher in the group of steroid use than in the control group. Conclusion: The use of steroid in patient with distal radius fracture may be a potential risk factor for extensor pollicis longus tendon rupture. Local steroid injection is not statistically related to extensor pollicis tendon rupture. Patients of distal radius fracture with steroid use need precaution if they have symptoms of extensor pollicis longus tendon rupture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
